# 790 RFID ## What is 790 RFID Technology? 790 RFID refers to a specific frequency band and protocol within the broader Radio Frequency Identification (RFID) ecosystem. In my experience working with asset tracking systems, I've found that 790 MHz systems often offer a compelling balance between read range and penetration, especially in challenging industrial environments. My personal view is that this band is underutilized but holds significant potential for specific use cases where UHF (860-960 MHz) might face interference or where longer ranges than HF/NFC are required. ## Technical Specifications and Parameters of 790 RFID Products For engineers and integrators, understanding the precise technical specifications is crucial. Below are detailed parameters for a typical **790 RFID** reader module. *Please note: These technical parameters are for reference data only. Specific needs require contacting backend management.* **Model:** TIANJUN-TJ790-IPX * **Operating Frequency:** 790 MHz ± 5 MHz * **Protocol Support:** ISO 18000-63 (EPCglobal Class 1 Gen 2), Custom TIANJUN protocols for high-security applications. * **Chipset Code:** TJ790-CORE-A1 (Proprietary TIANJUN ASIC) * **Output Power:** Adjustable from 10 dBm to 30 dBm (FCC/ETSI compliant variants available). * **Read Range:** Up to 15 meters with a standard tag, dependent on environment and antenna. * **Interface:** Ethernet (10/100 Mbps), RS-232, RS-485, GPIO. * **Antenna Ports:** 4 x RP-TNC connectors for TIANJUN's high-gain antenna array. * **Power Supply:** 12-24 VDC, PoE+ (IEEE 802.3at). * **Dimensions:** 220 mm (L) x 145 mm (W) x 35 mm (H). Mounting hole spacing: 200 mm x 125 mm. * **Operating Temperature:** -30°C to +70°C. * **Firmware:** Field-upgradable with TIANJUN's secure Over-the-Air (OTA) platform. My skill in system integration was truly tested when I configured a network of these TIANJUN readers for a large automotive warehouse. The precise control over the 790 MHz frequency allowed us to create reading zones without cross-talk, which was a problem they faced with standard UHF equipment. ## Entertaining Applications of 790 RFID Beyond logistics, **790 RFID** has found a fun niche. One innovative entertainment application is in large-scale interactive theme park experiences. For instance, guests can wear a 790 RFID wristband that interacts with hidden readers throughout a park, triggering personalized audio effects
